Patents generally last for 20 years from the first date of filing for priority. Patents filed prior to 1995 in the USA, however, may have a duration of 17 years from the date of ISSUE, or 20 years from filing, whichever is longer.
Patents on medicine often obtain statutory extensions, under US law, for certain delays caused by FDA review. This can substantially increase the patent duration beyond 20 years.
